I'd say the car is fragile.........
compared to the es300. Now this is more apples-apples.
at 67000 miles, my es300 feels more solid than this 350.
also, from the loaner car I have, the wood & plastic on the center console isn't too good, and squeaks a little on very slightly rough roads. when you push on the wood, it makes the same squeaks.
so yeah, in that sense, it is more fragile.
